Oilgear PVM-046 Variable Displacement Hydraulic Pump is a rugged, variable-displacement axial piston pump designed for hydraulic systems requiring flexibility, efficiency, and reliable midrange hydraulic output. With its maximum displacement of 46 cc/rev, this model offers an excellent balance between hydraulic capacity and precise control, making it ideal for medium-duty industrial and mobile hydraulic applications where flow often varies during operation.

The pump is designed for open-loop hydraulic circuits, allowing system integration to remain straightforward while still delivering responsive and efficient performance. PVM-046 supports continuous operating pressure of 260 bar, enabling it to work reliably under demanding load conditions without affecting the pressure stability or operational consistency. The maximum rating for its rotational speed is 2400 RPM, thus offering even greater flexibility in equipment that requires adaptable flow dynamics together with high speeds.

This is suitable for systems that require medium to high fluid delivery, such as for industrial machinery, material-handling systems, compact hydraulic presses, mobile equipment and auxiliary hydraulic circuits. Its ability to vary displacement ensures effective power utilization, lower heat generation, and accurate flow output to match current system demand.

The PVM-046 features Oilgear's proven axial-piston design with hardened internal components, a balanced rotating group, and precision-machined pistons internally. This construction enhances wear resistance and provides long service life. The pump operates well with a wide range of hydraulic fluids, including low-lubricity and specialty hydraulic oils, thus giving excellent adaptability to systems that require flexibility in fluid selection.

Due to its variable-displacement capability, the pump reduces energy consumption and is thus ideal for modern hydraulic systems that focus on efficiency optimization and reduced lifetime operating costs. With a compact build, flexible porting options, and high-performance control characteristics, PVM-046 is a go-to choice for system designers and OEMs requiring a reliable, adaptable mid-capacity hydraulic pump.
